Why not use something like:

----[ command 'apt-cache search rss' ]----------------------------------
libapache-mod-index-rss - Output RSS indexes of website content
libxml-rss-perl - Perl module for managing RSS (RDF Site Summary) files
python-pyrss2gen - A Python interface for generating RSS 2.0 feeds
rsskit.framework - GNUstep framework for parsing and manipulating RSS feeds
------------------------------------------------------------------------

I my self have coded an RSS feeder in php5 for my website  where  I  can
put one info per file in a RSS-Directory and they will be  put  together
into and rss-feed.  Also I can set expiration time by message...

If you know, the syntax of RSS-Feed files, you can  create  them  easyly
using php5, perl, python or even a BaSH script.
